Mitigating pesticide risk on bee pollinators and angiosperm biodiversity in the Ndop wetlands: A conservation approach.

This study aimed to assess the risk of pesticides on bee pollinators and propose strategies to conserve entomophilous angiosperm species in the Ndop wetlands. Results showed that the applied pesticide doses were often excessive, increasing the exposure toxicity ratios (ETR). Among the pesticides, insecticides posed the highest risk to bee pollinators, with Emamectin benzoate (ETR=591.

Controlling Culex pipiens: antagonists are more efficient than a neonicotinoid insecticide.

Species vulnerability to pesticides depends on physiological sensitivity, the potential to recover, and the ecological context. We assessed the vulnerability of the mosquito Culex pipiens to a repeated treatment with thiacloprid in outdoor microcosms with and without antagonists (competitive and predatory invertebrates). Microcosms were treated repeatedly (three times) with thiacloprid at a concentration of 0.

Influence of competing and predatory invertebrate taxa on larval populations of mosquitoes in temporary ponds of wetland areas in Germany.

Abundances of mosquito larvae and associated invertebrate communities were assessed in 27 temporary ponds during the spring season in wetland areas of Germany. Four genera of mosquitoes were identified: Aedes, Anopheles, Culex, and Culiseta. We focused our analyses on Aedes spp.
